BLE reconect problem after 18-19 min connection

Hello. I have encountered such a problem. My device (ble client) connects to the ble server once every 5 seconds, the rest of the time it sleeps. Each time before going to bed, I disconnect, and after waking up I call the connection. After 18-19 minutes of work, my application freezes. It only respo...

Re: Intermittent sleep without reconnecting BLE

Hi Swargir , Why not keep the connection and turn on bt light sleep? E.g., Set the connection interval to 2s. I think the power consumption will be less than the case doing reconnection every 5s. I use a light sleep that breaks the connection. Is it possible to fall asleep without reconnecting BLE?

Re: Esp32-arduino-fuel gauge

Hi. I would do so. I use Arduino IDE/Platformio 1) For ESP32 example. https://github.com/nkolban/ESP32_BLE_Arduino/tree/master/examples/BLE_server In it, add a cyclic reading of the analog inputs. Depends on what indicator from the bike will be connected through (max 3.3v voltage. divider is needed)...

Intermittent sleep without reconnecting BLE

Hi all. I’m developing a device based on ESP32-WROOM-32d. The device acts as a BLE-client and polls the BLE-server(cc2650) every 5 seconds. The rest of the time he sleeps( light sleep ). The problem is that waking up and reconnecting takes a lot of time and the consumption is almost the same as not ...
